[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When implementing: Figure 1-4 As shown, a portable box girder steel mold rust removal device comprises: a moving trolley 1, a push rod 101 is arranged on the top of the moving trolley 1, a laser rust remover 103 is arranged on the bottom of the moving trolley 1, a baffle 102 is fixedly connected to the bottom of the moving trolley 1, and a rust removal chamber is formed on the inner side of the baffle 102; a ventilation structure 2 is arranged inside the moving trolley 1, and the ventilation structure 2 is used to discharge the smoke generated during the rust removal process from the inside of the rust removal chamber; a filtering structure 3 is arranged inside the ventilation structure 2, and the filtering structure 3 is used to filter and intercept the smoke; the filtering structure 3 comprises a connecting cylinder 304, and the surface of the connecting cylinder 304 is provided with evenly distributed through grooves, and the inner side of the connecting cylinder 304 is fixedly connected with two mounting cylinders 307, and the surface of the mounting cylinder 307 is provided with evenly distributed filter holes, and the inner side of the mounting cylinder 307 is fixedly connected with a filter element 308, and the filter element 308 is an activated carbon material component;

[0023] The mobile trolley 1 is placed on the inner side of the box beam steel mold, and the push rod 101 is pushed to move the mobile trolley 1 along the inner side of the box beam steel mold to remove rust after starting the laser rust removal device 103. The operation is simple and the cleaning can be carried out quickly. After use, the equipment can be quickly transferred by the mobile trolley 1, which is convenient for carrying and transportation. During the rust removal process, the rust removal cavity formed by the baffle 102 can reduce the space for the smoke and dust to drift during the rust removal process. The laser head can emit a laser beam focused on the metal surface to form an irradiation point, which produces a strong thermal effect and photomechanical effect on the rust layer on the metal surface, causing the rust layer to heat up rapidly and undergo physical or chemical changes. By adjusting parameters such as laser power, scanning speed, and focusing distance, the depth and range of rust removal can be controlled to achieve an ideal cleaning effect.

[0024] After the smoke is guided to the inside of the installation cylinder 307, the filter element 308 made of activated carbon material can absorb harmful substances and odors in the smoke. The setting of the filter holes can filter large particles of smoke, avoiding air pollution caused by direct emission.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the ventilation structure 2 includes an air inlet chamber 201 opened inside the mobile trolley 1, an air inlet slot connected to the rust removal chamber is opened on the inner bottom wall of the air inlet chamber 201, a mounting chamber 204 symmetrically distributed with the air inlet chamber 201 is opened inside the mobile trolley 1, a discharge slot connected to the rust removal chamber is opened on the inner bottom wall of the mounting chamber 204, an air outlet chamber 202 located on the side of the mounting chamber 204 away from the air inlet chamber 201 and connected to the mounting chamber 204 is opened inside the mobile trolley 1, a fan 203 is arranged inside the air outlet chamber 202, a partition 205 is fixedly connected to the inner wall of the mounting chamber 204, and uniformly distributed connecting pipes 206 are embedded and installed on the surface of the partition 205, and the aperture of the connecting pipe 206 is larger than the pipe diameter of the mounting tube 307;

[0026] The fan 203 is preferably an exhaust fan 203, and the air inlet chamber 201 can connect the rust removal chamber with the outside world. A filter is provided on the top of the mobile trolley 1. The method of using the filter to filter impurities in the airflow is a relatively mature component in the application of the prior art, and will not be described in detail here.

[0027] The air inside the air outlet chamber 202 and the installation chamber 204 is discharged through the fan 203, so that a negative pressure is formed inside. Under the joint action of the discharge slot, the rust removal chamber, the air inlet slot and the air inlet chamber 201, the outside air enters the installation chamber 204 and the air outlet chamber 202 to form an airflow. During the air flow, the smoke and dust generated during the rust removal process inside the rust removal chamber can be entrained and introduced into the installation chamber 204, and can be filtered and discharged under the action of the filtering structure 3. At the same time, the gas flow process can be used to dissipate the heat generated during the use of the laser rust remover 103, thereby optimizing the working environment of the laser rust remover 103.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inner bottom wall of the installation cavity 204 is provided with evenly distributed placement grooves, the top of the mobile trolley 1 is provided with through holes corresponding to the placement grooves, the inner wall of the placement groove is slidably connected with a pressure plate 301, a spring 302 is fixedly connected between the bottom of the pressure plate 301 and the inner wall of the placement groove, and the top of the mobile trolley 1 is fixedly connected with a plurality of groups of card blocks 303, each group of card blocks 303 has two, two adjacent card blocks 303 are symmetrically distributed with the through hole as the center, the cross-sectional shape of the card block 303 is an inverted "L" shape, and the inner side of the card block 303 is provided with a card groove The lower end of the connecting tube 304 passes through the through hole and extends to the inside of the placement groove, and the bottom of the connecting tube 304 contacts the top of the pressure plate 301. A rotating plate 305 is provided on the top of the connecting tube 304. The top of the rotating plate 305 is fixedly connected to a limiting rod 306. The two ends of the limiting rod 306 extend to the inside of two adjacent slots respectively. The bottom of the rotating plate 305 is fixedly connected to a rotating shaft 309. The lower end of the rotating shaft 309 passes through the connecting tube 304 and is rotatably connected to the inner wall of the connecting tube 304. A spring 310 is provided on the surface of the rotating shaft 309.

[0029] The connecting tube 304 is inserted into the installation cavity 204 through the through hole, so that the lower end thereof is inserted into the placement groove and the pressure plate 301 is pressed to compress the spring 302. During the placement process, the limiting rod 306 and the block 303 are staggered. After the installation is in place, the rotating plate 305 is rotated to move the limiting rod 306 to the inner side of the block 303. At this time, the spring 310 can be tightened. After the connecting tube 304 is loosened, the connecting tube 304 can be moved upward for a distance as a whole under the action of the spring 302, and then the two ends of the limiting rod 306 can be driven to insert into the two slots, completing the effect of limiting the position of the rotating plate 305. The installation of the connecting tube 304 is completed. At the same time, the installing tube 307 is connected to the adjacent connecting tube 206, so that the discharged airflow can be filtered through the filter element 308 and the filter hole.

[0030] As the filtration proceeds, the impurities inside the installation cylinder 307 gradually increase, the weight increases and then presses down the pressure plate 301 to compress the spring 302, and at the same time drives the limit rod 306 to separate from the slot to release the limit on the rotating plate 305. At this time, under the action of the spring 310, the limit rod 306 and the block 303 can be staggered when the rotating plate 305 is reset, so as to remind the user that too many impurities are adsorbed and need to be cleaned and replaced, so as to avoid excessive adsorption of impurities affecting the normal flow of air.

[0031] When the utility model is in use, the mobile trolley 1 is placed on the inner side of the box beam steel mold, and the push rod 101 is pushed to move the mobile trolley 1 along the inner side of the box beam steel mold to remove rust after the laser rust removal device 103 is started. At the same time, the fan 203 is started to discharge the air inside the air outlet cavity 202 and the installation cavity 204, so that negative pressure is formed inside. Under the joint action of the discharge slot, the rust removal cavity, the air inlet slot and the air inlet cavity 201, the outside air enters the installation cavity 204 and the air outlet cavity 202 to form an airflow. During the air flow, the smoke and dust generated during the rust removal process inside the rust removal cavity can be wrapped together. The impurities in the installation cylinder 307 gradually increase as the filtration proceeds, and the weight increases, thereby pressing down the pressure plate 301 to compress the spring 302, and at the same time driving the limit rod 306 to separate from the card slot to release the limit on the rotating plate 305. At this time, under the action of the clockwork 310, the limit rod 306 and the card block 303 are staggered when the rotating plate 305 is reset, so as to remind the user that too many impurities need to be cleaned and replaced, so as to avoid excessive impurities affecting the normal flow of air.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
